Make sure you have the required Berkeley DB libraries AND headers installed.
You can download the latest version from http://www.sleepycat.com.
If you have installed BDB in a non standard location use the
--with-bdb=/path/to/bdb configure option and make sure
your linker is configured to check for libraries there.
configure: error: Berkeley DB library required but not found!

But:

[sb@webdev netatalk-2.0.1]$ ll /usr/local/lib/libdb-4.2.so
-rwxrwxr-x 1 sb sb 790425 Nov 7 15:52 /usr/local/lib/libdb-4.2.so

Solution

Either -
# ln -s /usr/local/lib/libdb-4.2.so /lib/libdb-4.2.so

Or -
# echo /usr/local/lib >> /etc/ld.so.conf && /sbin/ldconfig
